1. A system for use in the detection or measurement of at least one characteristic relating to a chemical environment, the system comprising:

  • an optical fibre arranged to receive light from an optical source;

    the system being adapted to let a gas derived from said chemical environment diffuse into the optical fibre thereby altering the optical properties of the optical fibre, so that changes in the optical properties of the optical fibre due to the in-diffusion of said gas can be determined by optical signal detection and signal analysing means for deriving from the determined changes at least one characteristic value representing the chemical environment.
